ABSTRACT
【Objective】 To evaluate the performance of electrochemiluminescence immunoassay (ECLIA) in detecting HIV antigen/antibody in blood screening. 【Methods】 A total of 128 donors, reactive to anti-HIV(ELISA)testing, from September 2016 to September 2020 were enrolled, and seven samples were reactive to double anti-HIV reagents, among which 6 were confirmed by WB, 1 confirmed by NAT as negative.Two group of donors, reactive to solo anti-HIV reagent but being confirmed negative by WB(n=121) vs.randomly selected donors non-reactive to ELISA + NAT(June to September 2020, n=1360), were subjected to HIV antigen/antibody testing using ECLIA to compare the testing results, including concordance rate, sensitivity and specificity. 【Results】 The ECLIA results remained non-reactive for 1360 samples initially non-reactive to both ELISA and NAT.The concordance rate of anti-HIV reactivity by ECLIA and ELISA+ WB were 100%(6/6). For 122 samples, reactive to ELISA anti-HIV testing but nonreactive to confirmatory testing, 4(3.28%)of them were reactive to HIV antigen/antibody testing and 118(96.72%) nonreactive, with the concordance rate of ECLIA and ELISA at 96.88%(124/128). The sensitivity, specificity and false positive rate of ECLIA and ELISA were 100% vs 100%, 99.73% vs 91.77%, and 0.27% vs 8.23%, respectively. 【Conclusion】 ECLIA for HIV antigen/antibody detection has good sensitivity and specificity, which can meet the requirements of blood screening, and the false positive rate is lower than that of ELISA, adopted commonly in blood bank at present.
ABSTRACT
Objective:To study the short-term effect of early application of intestinal microecological therapy after gastric cancer surgery.Methods:A retrospective analysis was made on 96 patients with early and middle stage gastric cancer who underwent surgical treatment in the department of gastrointestinal surgery of Shulan (Hangzhou) Hospital from June 1, 2020 to May 31, 2021. Among them, 48 patients in the observation group were given enteral nutrition support treatment in the early stage after operation and intestinal microecological preparation, while the control group of 48 patients in the early postoperative were given enteral nutrition support. The serum total protein, albumin, prealbumin and other nutrition related indexes and immune related indexes such as CD4 + , CD8 + , CD4 + /CD8 + were detected before and 7 days after operation. The clinical indexes such as the time of first anal exhaust and the incidence of infectious complications were recorded. Results:There was no significant difference between the two groups in preoperative serum total protein, albumin, prealbumin and immune related indexes such as CD4 + , CD8 + , CD4 + /CD8 + ( P>0.05). 7 days after operation, the above indexes in the observation group were significantly higher than those in the control group (all P<0.05). The anal exhaust recovery time of observation group was faster ( P<0.05); There was no significant difference in the incidence of postoperative infectious complications between the two groups ( P>0.05). Conclusions:Early application of intestinal microecological agents in patients with gastric cancer after operation can significantly improve the nutritional status and immune function, promote the recovery of intestinal function, and will not increase the incidence of complications.
ABSTRACT
Objective To evaluate the implementation and effectiveness of syphilis prevention and control in Hubei Province from 2011 to 2020, to summarize the experience and practice, to analyze the existing problems and causes, and to study and put forward policy and strategy suggestions, so as to provide reference for formulating the national “14th five-year plan” and carrying out the next step of prevention and control work. Methods The National STD Prevention and Control Management Information System, STD Prevention and Control New Media Health Service Platform, National AIDS Comprehensive Prevention Information System, and National Management Information System for the Prevention of AIDS, Syphilis, and Mother-to-Child Transmission of Hepatitis B were used to analyze and evaluate the completion of main prevention and control indicators in Hubei Province. Results Among the 16 evaluation indexes, 10 indexes including the effectiveness of syphilis promotion and training for various groups of people, the proportion of pregnant women undergoing syphilis testing in the monitoring and testing work, and the effectiveness of syphilis prevention and treatment, all met the requirements of the plan. In addition, some of the 5 indexes failed to meet the requirements of the plan. Conclusion Hubei Province has fairly fulfilled the work requirements of the Plan. It is still necessary to strengthen the syphilis prevention and control to ensure the urban pregnant women infected with syphilis and their infants to receive standardized STD diagnosis and treatment services, and the drug users in the drug maintenance treatment clinic to receive free syphilis testing, and to provide referral services for the syphilis antibody positive patients at AIDS voluntary counseling and testing points.
ABSTRACT
Objective:To investigate the predictive value of serum soluble urokinase-type plasminogen activator receptor (suPAR) combined with alpha-fetoprotein (AFP) and model for end-stage liver disease (MELD) score in short-term prognosis assessment of patients with chronic hepatitis B (CHB) related acute-on-chronic liver failure (ACLF).Methods:From January 2018 to May 2020, 66 patients with CHB related ACLF from Fuzhou First People′s Hospital were enrolled. After 90 days of follow-up, the patients with CHB related ACLF were divided into death group and survival group according to the outcome. Meanwhile, 30 patients with CHB were enrolled by simple random sampling method. The differences of serum suPAR in patients with CHB related ACLF and patients with CHB were analyzed. The values of suPAR, AFP and MELD score were compared between death group and survival group in patients with CHB related ACLF. The predictive value of suPAR, AFP, MELD score, Child-Turcotte Pugh score (CTP score) and suPAR combined with AFP and MELD score in the short-term prognosis of patients with CHB related ACLF were analyzed by area under the receiver operator characteristic curve (AUROC). Data were analyzed by two independent sample t test or non-parametric test. Results:The serum suPAR level of patients with CHB related ACLF was (9.6±0.8) ln ng/L, which was higher than that of patients with CHB ((8.0±0.3) ln ng/L). The difference was statistically significant ( t=14.533, P<0.01). The suPAR and MELD score of patients with CHB related ACLF in the death group were (9.9±0.7) ln ng/L and 29.6 (7.1) points, respectively, which were higher than those in the survival group ((9.4±0.7) ln ng/L and 21.0 (5.0) points, respectively). The AFP level in the death group was 45.9 (108.1) μg/L, which was lower than that in the survival group (209.3 (187.1) μg/L). There were significant differences in suPAR ( t=2.895, P=0.005), MELD score ( Z=4.708, P<0.01) and AFP ( Z=3.051, P<0.01) between the death group and the survival group. AUROC of suPAR (0.741, P=0.001), AFP (0.724, P=0.002) and MELD score (0.885, P<0.01) had predictive value for death in patients with CHB related ACLF. The sensitivities of suPAR, AFP, MELD score, CTP score and suPAR combined with AFP and MELD score were 84.6%, 73.1%, 88.5%, 96.2% and 84.6%, respectively, and the specificities were 75.0%, 72.5%, 70.0%, 52.5% and 92.5%, respectively. The AUROC of suPAR combined with AFP and MELD score was 0.871 ( P<0.01), which was higher than that of CTP score (0.793, P<0.01). Conclusions:Serum suPAR is increased in patients with CHB related ACLF. SuPAR combined with AFP and MELD score could apply in the prognostic value for patients with CHB related ACLF.
ABSTRACT
Objective:To explore the role of negative pressure drainage in the treatment of duodenal stump fistula after gastrectomy.Methods:The data of 36 patients with duodenal stump fistula admitted in our department from January 2016 to January 2020 were analyzed retrospectively.

The incidence of complications and healing time of intestinal fistula in the two groups were observed.Results:There was no significant difference ( P>0.05) in the incidence of complications between the observation group (5.56%) and the control group (11.11%). There was a significant difference in the mean healing time between the observation group [(12.83±6.25)days] and the control group [(23.33±4.64)days] ( P<0.05). Conclusions:Negative pressure drainage is beneficial to the healing of duodenal stump fistula, and does not improve the incidence of postoperative complications. It is safe and effective. It can be used as a conventional drainage for gastrectomy.
ABSTRACT
Objective@#To explore the surgical methods for children with contracture deformity on hands after burn.@*Methods@#From January 2014 to January 2018, 33 pediatric patients, a total of 42 hands with scar contracture deformities were reviewed. There were 24 males and 9 females, aged from 11 months to 6 years and 7 months. Among them, 20 hands were volar metacarpophalangeal joint contractures, 9 were volar interphalangeal joint contractures, 7 were dorsal metacarpophalangeal joint contractures (3 claw-shaped hands), 3 were hand back contractures, and 3 were palm contractures. Of the 42 hands, 36 hands were repaired with full-thickness skin grafts or split-thickness skin grafts, after the removal of contracted scar, and 6 hands were repaired with abdominal skin flaps, due to the tendon or bone exposure after the scar removal.@*Results@#Skin grafts on 31 hands were all survived after 2 weeks. However, the survival area of 3 skin grafts was about 90%, and 2 skin grafts survived about 80%. All of them healed well after dressing changing. The 6 hands repaired with abdominal skin flap healed well too. After 1-2.5 years of follow-up, finger scar contracture occurred in 4 hands with skin grafting, and they were performed scar excision and sheet skin grafting. Three hands were treated with Z-plasty, due to web space contracture. The function of other hands were normal, without contracture or deformity. The skin color and texture were similar to the surrounding skin, with limited pigmented. Scars on the edge of skin grafts was not obvious. Patients and their families were satisfied.@*Conclusions@#The sheet skin graft is the main method for postburn scar contracture in children′s hands. The abdominal skin flap should be considered, if tendon or bone is exposed, especially for large wound or multiple sites.
